Comment (by sboisvert):

 Just to make it easier for someone else who can actually fix the problem,
 it seems to be related to the fact that
 parse_tax_query()
 parses categories differently than tags/tax, the logic that was added for
 this in line 1695 is as follows:
 $q['category__in'] = array_unique( $q['category__in'] );
 Which seems to be different than the one in [15626], in that the one in
 [15626] casts as an array and then traverses and casts the values of the
 array as ints:
 $qv['category__in'] = array_map('absint', (array) $qv['category__in']);

 I suspect the behavior in [15626] might be the better one, but I wouldn't
 be able to say anything with any certainty if there is any valid reason
 why it was not implemented this way.

 Thank you,
